18th Century Mechanism Reconstruction for a Museum in France 

"Have you heard of Clickspring?"

Yes these were lines in the video thank you for transcribing them

I came, I snorted laughter, I stayed for the whole video.

Gold statement by Uri

@@thewolfin They bear repeating.

Thank you my friend!

So what does it do??

I agree, right up there with "Have you heard of Clickspring?" Haha

Yes,I agree.. and in a long Winternight after a long Summerday

I see, you have fun to work with materiel like this. That's great.👍

the universe neither knows of or cares about maths, it's a tool invented by man to incompletely describe and model some aspects of it.

@@axeman2638 ok grandpa

Lmao. Isn't he hilarious

The main differense is that Uri could achieve the same things without any of all those expensive machining tools. (And The machines he are using fit's the theme very well, i realy love the old late for example.)

@@sheep1ewe That seems a little unfair on Clickspring. He certainly has the machine tools and knows how to use them, but given that he also not only hand files gears but makes the files for it, it's certainly not that he "couldn't" do it without the machine tools.

@@fnordfnordsson4385 Yes, maybe my joke was a bit too far, i hawe the deepest respect for Cris and i watch every single video he made public.

Antikythera year 5... "This year we make the worlds not perfect screw by hand filing a 40kg block of forged steel down to a 2mm screw"

Love this channel and Clickspring.

Me too!

That makes sense. Good catch.

Yeah, I was gonna recommend running it across a stamp pad a few times to load it up.

If he made it not quite accurately but very nice looking, would that be a Parker Curve?

I think this is the curve where if you drop a ball on each side they connect in the middle regardless where on the curve you drop them and even if you drop them from different heights. It probably has a name but I can't remember.

​@@chrissibersky4617 It's a tractrix.

Finding a house broken and trained mathematician is hard these days; they’re all running wild and feral on the prairies.

We all chortled.

I laughed

Some of us guffawed.

I sniggered

I giggled. It made me doubt my masculinity, but there it is.

He's definitely one of my favorites as well. I love the goofiness, makes him real and not pretending to be someone else.

We all make mistakes. it’s when we learn from them, thats what matters the most, not the mistakes themselves.

😳

My channel is built on mistakes!!

I think it's because you typed "I don’t know why it’s taking me so long to say this but here it goes". That's why it took so long

I think its the "golden ratio"

@@jonpierce8342 they want to draw eyebrows?

@studer1679 no, I have a feeling the next one will be a tractrix. This one is a logarithm, Im not sure but I have a feeling choosing the length determines the base of the log you draw. They were used to solve equations graphically.

The mechanism somewhat dupcates the Logrithmic or Exponental curve which have a unique relationship betwenn X and Y which no other method of free hand drawing or tracing can duplicate. It may sound irrelevant now, however consider the time in which it was designed. No one had ever seen a true Log or Exponential curve at this point, they were approximated however no accurate representation was ever demonstrated. We take a lot for granted in our digital time, just look at a slide rule demonstration video. It is likely that anye reading this has a parent, grandparent, or relative that had to use them in school/life

"In 1728 the Italian scholar Poleni took up the theme again. He designed a tractional instrument (see Plate 10 [this mechanism]) and sent copies of it to three colleagues. In his covering letter he argued, again, that by means of his instrument the problem of the *quadrature [area] of the hyperbola* was now for the first time solved in a geometrically acceptable manner" www.gewina.nl/journals/tractrix/bos89.pdf It seems the context of this device is the ancient topic of Euclidean geometry, about whether things can be constructed with the most basic physical tools, (straightedge and compass) rather than by arithmetic. These devices construct transcendental curves without arithmetic, but they're still not a straightedge and compass, so some 18th century controversy perhaps. Or as that article so nearly puts it, "The motif of tractional motion as mechanical legitimation of transcendental curves"

Oh that was a great video, I come back to see it every now and then

I believe you meant "Machine Thinking"... :)

That's what I was looking for

What is that?

@@timsmith1589 it is a curve representing a logarithmic progression, reverse of an exponential progression.

Yes, or AI

Oh it _does_

Was wondering wich one it was. Thanks.

Then do it

@@andyb7963 I did it! I found a Buck 110 with brass bolsters and i did some terrible engraving with a dremel, but i did it. 😁

Same

Be bloody cold in the winter
